Operation

Phase Sequence Function

The Phase Sequence function determines if the 3 phases are live and the direction a motor

will turn if connected as indicated in Table 1.

1. Connect the three test leads to the power source

2. Observe that all three lights (L1, L2, L3) are active

3. Observe the directional indication lights.

4. If the direction indicated is counter-clockwise, reconnect any two wires until the

clockwise indicator is lighted.

5. If the clockwise indicator is lighted, label the power source "L1, L2, L3"

Motor Rotation Function

1. Make sure there is no voltage present.

2. Insert the test leads into the input terminals:

3. L1 - Black, L2 - Red, L3 - White. Attach the

other ends of the leads to the 3 phase motor.

4. Press and Hold the power button. The green

power indicator will light up.

5. Rotate the motor shaft clockwise (as viewed

from the end of the shaft). If the red clockwise

indicator is lit the 3-phase motor will rotate

clockwise if connected to the power supply

by the L1-L2-L3 sequence.

6. Rotate motor shaft counter-clockwise. If the

red counter-clockwise indicator is lit the 3-

phase motor will rotate clockwise if

connected to the power supply by the L1-L2-

L3 sequence.

7. If you want the motor to rotate counterclockwise, change the order of the connections to

L2-L1-L3 and the motor will rotate counter-clockwise.
